Submarine water supply pipeline system is an important approach to meet water resources for offshore island,since water shortage may af-fect the development of islands. Using adaptive pressurized system can improve the load adaptability and the energy-saving effect of submarine water supply pipeline. This article introduced the basic structure and principle of sea-crossing adaptive pressurized water supply piping system. By com-paring with conventional pumping station system,energy saving characteristics of adaptive pressurized system were analyzed. The water pump pres-sure and energy consumption of different days’water process lines were calculated and compared. The water pump power consumption process lines of two pressurized systems were separately drew and the energy-saving efficiency of adaptive pressure system were analyzed under the conditions of different water process lines. The results show that when the water process fluctuates wildly,using adaptive pressurized system can improve the en-ergy-saving efficiency of water conveyance system well.
